I mentioned to a colleague that I’d bought two lottery tickets for last weeks Euromillions draw instead of my usual 1 to double my chance at winning. He said “Yeah, that’s not how it works.” I’m sure he is right – but why?

He’s not right, you are. A second ticket doubles your odds unless the numbers on both are identical.
Imagine if the numbers were simple, just a single number from 1 to 100 was drawn for the winner. If you have a ticket you have a 1 in 100 chance, if you have a second ticket with a different number then it’s 2 in 100 odds.
